How to change menu hover color to white on my theme?

Hello,
When you look at my themes menu, you can see when you hover over the menu links, the hover color is red. That is good. What you can also see is that the link inside the red hover turns from white to black. I would like to keep it white and do not know how to approach it.

Hello,
I just noticed something else that is kind of weird. If you open the sub menu on More, then go to the menu item donate, the menu item more changes back to black. Is there anyway to keep it red?
It is like there are multiple hover colors and styles, I don't get this theme author at all.
